REVOLVING HEEL-PLATE.

SPECIFICATION forming part of Letters Patent No. 256,076, dated April 4, 1882.

Application filed August'25,1881. (No model.)

To all whom it may concern Be it known that I, JUDsoN L. THOMSON, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvementsin RevolvingHeel-Plates, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to heel-plates delo signed to be detachable and capable of revolving; and it consists in a novel construction and means of attaching a certain stiffening-plate to a revolving heel-plate, all as hereinafter more fully described, and specifically I5 set forth in the claims.

In the annexed drawings, Figures 1 and 2 .are side and inverted plan views, respectively,

' of a revolvingheel-plate constructed in accordance with my invention; and Figs. 3 and 4 are ,vertical sections ofa revolving heel-plate, illustrating the construction of the stiffening-plate and the means of'at-taching the same to the heel-plate.

Similar letters of reference indicate correspending parts.

A represents the heel-plate designed to be detachable and capable of revolving on the heel. Said plate is made of the usual circular form, and secured to the heel by a screw, n, in-

0 serted through the center of said heel-plate.

It is usually formed of leather or rubber, and. stiffened by a metal plate applied to the upper face of the heel-plate. Said stiffening-plate has heretofore extended completely across the 5 heel-plateand protruded atthe periphery thereof, thereby impairing the external finish and appearance of the heel. To overcome this defeet I employ ametal plate, 7', which is of smaller circumference than the heel-plate and o countersunk in the upper surface thereof, and secured thereto by a central tubular shank or stud, s, which is integral with the plate 1', and is expanded in the flaring screw-hole. in the heel-plate, as illustrated in Fig. 3 of thedrawings. By means of prongs or spurs c on the 5 under side of the plate 4", pressed into the upper surface of the heel-plate, the former is prevented from turning on the latter.

It-will be observed that by the described construction of the plate 1 and its connection with the heel-plate the exterior of the latter is not defaced by the protrusion of the stiffening-plate, and the fastening of said stiffeningplate is made to serve the additional function of an anti-friction washer, which has heretofore been separately inserted in the countersink for the screw which attaches the heelplate to the heel.

Having fully described my invention, what I claim is- 1. The combination, with a revolving boot or shoe heel plate, of the metal plate 1", secured to said heel-plate by the tubular studs, attached to the metal plate and expanded within a tapering countersink in the opposite side of the revolving heel-plate,substantially as described and shown.

2. The combination, with a revolving boot or shoe heel plate, of the metal plate 1", countersunk in said heel-plate, and prevented from turning by spurs eon the face of the metal plate, and secured to the revolving heel-plate bythe tubular stud s, which is attached to the plate 1, and expanded within a tapering countersink in the opposite side of the revolving heel-plate, substantially in the manner described and shown.

In testimony whereofl have hereunto signed my name and aflixed my seal, in the presence of two attesting witnesses, at Syracuse, in the 80 county of Onondaga, in the State of New York, this 8th day of August, 1881. p
